摘要

针对在光网络中为分布式并发业务提供定制服务的问题

提出了一种负载均衡的多源多路并行调度策略

将网络负载和应用负载均衡分担在不同的资源节点。通过仿真验证

与普通的单源单路最短路策略和多源多路最短路并行传输策略相比

该策略能够有效地降低分布式业务的阻塞率。以分布式服务GridFTP在可重构光网络实验床上的应用为例

通过实验验证了该策略的可行性和有效性。实验结果表明

综合考虑应用资源和网络资源的负载均衡

可以有效降低分布式业务在网格系统中的处理时间

提高系统性能。

Abstract

To provide customized services for concurrent distributed applications in optical networks

a load balanced multi-source multi-path parallel scheduling strategy was proposed

in which the network load and applications load are equally shared in different resources nodes. Simulation results validate that this strategy can effectively reduces the block ratio of distributed services compared with single-source single-path strategy and multi-source multi-path strategy. A testbed of reconfigurable optical network for distributed services is designed to validate the feasibility and effectively of the load balanced parallel scheduling strategy through an example of distributed GridFTP service. The experiment results show

considering the load balance of the application resources and network resources together

this strategy with can successfully decrease the process time of distributed services in grid system and improve system performance.
